To all whom t may concern.'

Be it known that l, DONALD S. BAuuows,

a citizen of the United States, residing at Rochester, in the county ofMonroe and State of New York, have invented certain new and usefulImprovements in Gar Underframes; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same.

My invention relates to improvements in underframes for railwayy carsand, more particularly, to a strong, reliable and efficient metallicstructure adapted to be ap plied generally to wooden underframe cars toreinforce the underframes thereof, thereby adapting said cars for useunder modern service conditions.

To this end, one of the principal features of the invention, generallystated, is to provide a metallic struct-ure, said structure being usedto reinforce the car sills and designed to receive the bufhng andpulling shocks which are transmitted thereto by the draft rigging.

The invention, broadly stated, consists in providing a car underframe ordraft arm in which the center sill reinforcing members overlie thebolster and are connected thereto by means of an interposed gusset plateextending forwardly and rearwardly of the bolster, said gusset platebeing connected to the inner ends' of the draft sills.

j. Another object of the invention resides in the provision of a carunderframe including in combination longitudinally arranged car sillreinforcing members adapted tof overlie the bolster and having connectedthereto depending draft members, a gussetr plate bridging and connectingthe reinforcing members and overlying the bolster, and means including aplurality of abutment members or blocks advantageously located adjacentthe front and rear portions of the bolster, said abutmenty members beingadapted to eectively assist in resisting the strains to which theinterconnected parts are subjected in service.

Another object of the invention is to provide a comparatively simple"metallic structure for car underframes involving `a single gusset platebridging' the center sill reinforcing members Vand connecting the 'sametolthebvolster andto each. other, said center draft sill.

A further object of the invention is to provide a draft arm including incombination center sill reinforcing members adapted to be connected by arelatively long gusset plate overlying the bolster and extendingforwardly and rearwardly thereof, said reinforcing members being furtherconnected by cross braces or tie members upon opposite sides of thebolster andlnear the ends of said gusset plate.

There are other features of the invention as will be pointed outhereinafter in connection with the detailed description of my inventionillustrated in the accompanying drawings inwhich- Figure 1 is a planview of my improved metallic draft arm.

Figure 2 is a vertical cent-ral longitudinal sectional view through theconstruction shown in Figure l.

Figure 3 is a vertical transverse sectional view on the line 3-3 ofFigure 2 viewed in the direction of the arrows.

Referring to the drawings in which similar reference charactersdesignate corresponding parts in the several views, the wooden centersills of railway cars are adapted to be reinforced by means oflongitudinally arranged angle members l-1 adapted to overlie the bolster2. The bolster is formed with upper flanges 3 and lower flanges 4, saidflanges being connected by means of the web portion of the bolster, asshown. Braces or tie members 5 connect the reinforcing members, rivets 6uniting the bent or flanged ends of said braces to the vertical flangesor center sill reinforcing members. interposed between the upper flangeof the bolster and the center sill reinforcing members is a gusset plate7, said plate being preferably connected to the center sill reinforcingmembers by means of a plurality of rivets 8 and to the upper flanges ofthe bolster by a plurality of bolts 9.

Arranged adjacent the forward edge of the upper flange of the bolsterand centrally thereo'fis an abutment member or vblock 10, said blockbeing connected to theunder`` side ofthe gussetplate by means of rivetsv11. The ends of the block` preferably eX- tend beyond the verticalflanges of the center sill reinforcing members and are preferablylocated between the draft sills, as shown. Abutment members or blocks 12are arranged immediately adjacent and contacting the rear edge of theupper flange of the bolster, each of said blocks 12 being connected tothe horizontal flange of the center sill reinforcing members andinterposed gusset plate by means of rivets 13.

rlhe abutment blocks 1() and 12 are advantageously positioned toresistthe butling and pulling shocks imparted to the underframe, andmore particularly the center sill reinforcing members, the forwardabutment block-10 havingits end portions overlying the rear abutmentblocks, as best shown in Figure 1. r

r-lhe dra-ftsills lil are preferably of channel shape, the inner ends ofsaid sills, and more particularly the inner upper flanges thereof beingconnected to a horizontal flange of the center sill reinforcing membersand the interposed gusset plate 7 by some of the rivets 8 hereinbeforereferred to. lnterposed between the horizontal flange of each centersill reinforcing member and the upper flange of the adjacent draft sillis a filler plate lor strip 15, said filler strip being preferablypositioned in longitudinal alinement with and forwardly adjacent thegusset plate 7. A plurality of rivets 1G preferably disposed inlongitudinal a-linement with the rivets 8 serve to unite the fillermember with the center sill reinforcing member and the adjacent draftsill. A bottom tie plate 1T connects the lower horizontal flanges of thedraft sills, said tie plate being secured to the draft sill flanges bymeans of rivets 18. The tie plate 17 is preferably located beneath theforward end of the gusset plate and spaced from the inner ends ofthedraft sills.

,Cheek plates 1 9 are riveted to theY feces of the dra-ft sills, saidcheek plates being provided with slots 2O adapted to register with slotsin the draft sills for receiving a key ofA the well .known Farlow draftrigging equipment, said hey and rear block or follower being shown indotted lines in Figure 2.

lliliiile l have for convenience illustrated the invention as applied tothe three-key type of draft rigging, it will of course be apparent tothose skilled in the art that the draft arm construction shown may beadvantageously utilized with the more modern type of draft riggingillustrated, for

example, in the Symington Patent No.v

1,097,738, issued May 26, 1914.

A draft arm constructed in accordance With-my present invention permitsthe buffing-and pulling loads to be. eifeetively `transmitted to the carcenter sills andthe bolster,

the arrangement of abutment blocks and interposed gusset plate providinga simple, strong and easily assembled connection. l have described myinvention in detail so that its nature and the manner of using it may befully understood by those skilled in the art. However, the specificterms herein are used-in-their descriptive sense rather than in theirlimiting sense, and the` scole of the invention is defined in theclaims.
